Abstract
A modified epoxy resin composition having improved flexibility which comprises a reaction product of an epoxy resin and a synthetic rubber reactive with an epoxy resin in the presence of a nonionic or anionic surfactant, which has uniform and stable dispersion state of the rubber in epoxy resin without increase of viscosity. The epoxy resin composition is useful as a material for adhesives and coating agents.
Claims6
An epoxy resin composition which comprises a reaction product of 100 parts by weight of an epoxy resin and 2 to 100 parts by weight of a synthetic rubber reactive with the epoxy resin and incorporated in the reaction product 1 to 20 parts by weight of a nonionic or anionic surfactant.
A process for preparing an epoxy resin composition, which comprises reacting 100 parts by weight of an epoxy resin with 2 to 100 parts by weight of a synthetic rubber reactive with an epoxy resin in the presence of 1 to 20 parts by weight of a nonionic or anionic surfactant.
